' 1 claim. (01191-58) This invention relates to label pasting machines,and has for one of its objects the provision of a machine of this typewherein the stripperiingers are of improved andnovel .constructionwhereby wear on the fingers may be readily taken up. My constructionalso providesfor replacement of the ngers when necessary, withoutentailing the expense of installing a new mount therefor.

In the accompanying drawing: Fig. l is a fragmentary elevational viewpartly in section of an embodiment of my invention;

Fig. 2 is a plan view thereof; y Fig. 3 shows the stripper ringerconstruction on an enlarged scale; and

Fig. 4 shows a jig or `gauge employed for setting the lingers.

Referring to the drawing in detail: 2 designates the paste roller, and 4the presser rollers -of a label pasting machine. The labels are fedacross the front' of the -machine -between the paste roller and thepresser rollers. I have shown a label at 6 passing through the machine.This is conventional design and will not be discussed in any furtherdetail.

To the rear of the paste or glue roller 2, extending, transversely/.ofthe machine and mounted`in the side frames of the ,machine'is a ngerbar' 8. This bar carries a plurality of strippery inger or stripperblade holders III. These blade holders are threaded upon the finger bar,and keyed thereto by key I2, this key preventing rotative movement ofthe holders relativelyto the linger bar and relatively to each other.

Each blade holder is provided with a rectangular aperture I4 for thereception of the shank of the stripper blades or lingers. Each bladeholder is also bored to receive a Vguide bar I6 which passes through thebank of holders.l

The stripper blades or ngers are designated I8.. These are flat metalplates, each provided with a reduced shank 20, the Shanks being insertedinto the aperture I I. The blades are heldv in place in their holders byscrews 22.

`From the description given thus vfar, it will be seen that the stripperlingers or blades I8 are individually adjustable in their holders, andthat when a blade is worn away so that it is no longer usable it can bereplaced without the necessity of replacing the mount also.

For the purpose of setting the blades initially.'

finger mounted in and for setting them from time to time thereafter whenthey' have been Worn away to some extent, I provide a jig or gauge 24 onthe bed of the machine. This .iig is an elongated iiat metal 5 stripwith a boss 26 at one. end which is of the proper-size to receive ablade holder I0. The 4other end of the jigis provided with a boss 28 Ihaving a triangular shaped depression 30 in its .-face. In practice a"holder1I0 with a blade I8 1o therein is placed over the boss 26. Theblade is then moved in its aperture Idfin the blade holder unta the freeend of the seine nts inte thedepression 30. The screw 22 of the holderis then tightened to-secure the blade to the holder l5 in correctposition. Initially all ofthe blades are set in this fashion, and it.will be quite apparent that all of the blades will be correctly set sothat their contact with the surface of the glue or paste roller 2 isuniform. As the blades wear away due to their contact with the roller 2,it is merely necessary to remove the holder and blade and reset withvthe jig. vWith this arrangement, it is no longer necessary to replace ablade or finger which has been worn, inasmuch as each blade 25 can bereset from time to time until it hasbeen worn away practically up to theshank 20. Not only does this eiect a saving in blades so far as themachine owner is concerned, but it. ensures accuracy with respect to thecontact of the blades with the glue roller, with the assurance that theblades will perform their stripping functionin the most eicient manner.

It is to be understood that changes `may be made in the details ofconstruction and arrangevv ment of parts hereinabove described withoutdel parting from the spirit and scope of my invention.

What I claim is:

In a machine of the class described, a stripper finger bar, a pluralityof stripper i'lnger mounts.

40 said bar passing through said mounts and held against rotationrelatively thereto, a guide bar passing through said mounts parallel tosaid linger bar, each of said mounts being provided, above the guidebar, with an aperture, a stripper each aperture, the lingers beingindividually slidable for adjustment in said aperture transversely ofthe axis of the guide bar.

-and a screw passing through the bottom ofeach mount into engagementwith the underside of each nger to hold the latter in adjusted position.
